New tuna feed developed by Ridley

In partnership with Clean Seas Tuna, Ridley Corp has produced a new formulated fish food enriched with vitamin E and C.

The feed has been developed for the Port Lincoln tuna industry, in South Australia. The new food outperforms traditional pilchard fish feed in weight gain, condition and food conversion ratio. Ridley said it also had higher flesh quality and provided superior customer taste feedback.

The first commercial trial of 2,000 fish fed exclusively on the new feed since their capture, produced excellent results when sold at the famous Tsukiji fish market in Tokyo.

Ridley Aqua-Feed technical manager Dr Richard Smullen said the fish fed on the new Ridley feed converted their feed 30 per cent more efficiently than those fed on pilchards.
